R. Aoki et Tj. Prusa, PRODUCT DEVELOPMENT AND THE TIMING OF INFORMATION DISCLOSURE UNDER USAND JAPANESE PATENT SYSTEMS, Journal of the Japanese and international economies, 10(3), 1996, pp. 233-249
This paper examines the consequences of the differences in the timing
of information disclosure between the U.S. and Japanese patent systems
. Under the Japanese system it is possible for a firm to apply for a p
atent, knowing the exact specifications of a rival's patent applicatio
n. In contrast, in the United States the only way a firm learns about
a rival's innovation is upon the actual granting of the rival's patent
. We argue that this difference enables Japanese firms to coordinate t
heir R&D efforts better than their U.S. counterparts and that this, in
turn, leads to smaller quality improvements under the Japanese system
. We show that the creation/diffusion tradeoff of patents can be influ
enced not only by the scope and length of patent protection but also b
y other features of the patenting process. J. Japan. Int Econ., Septem
